Protests have erupted across Iran after the government unexpectedly announced it was rationing petrol and increasing its price. At least two people have been killed.
Prices rose by at least 50% on Friday as subsidies on petrol were reduced.
The authorities say they want to free up money to help the poor.
Iran is already suffering economically due to stiff sanctions imposed by the US after Washington decided to pull out of the 2015 Iran nuclear deal.
One person was killed during protests in the central city of Sirjan. State news agency Irna said there were clashes with police when protesters attacked a fuel storage warehouse on Friday and tried to set fire to it.
Several more people were injured. A protester also died in the city of Behbahan.
Other cities were also affected including the capital, Tehran, Kermanshah, Isfahan, Tabriz, Karadj, Shiraz, Yazd, Boushehr and Sari.
In several cities, dozens of angry motorists blocked roads by turning off car engines or abandoning vehicles in traffic.
